Question 1.
What is I_DS in a MOSFET?
Show hintHide hint
Think about the current's pathway in a MOSFET.
Question 2.
What does V_th represent?
Show hintHide hint
Consider the voltage needed for conduction.
3Question 3.
What happens to I_DS when V_GS is below V_th?
- True
- False
Show hintHide hint
Recall how V_th affects channel formation.
4Question 4.
In which region does I_DS primarily depend on V_GS?
- Triode region
- Saturation region
- Dissipation region
Show hintHide hint
Think about what happens to the current in saturation.
Question 5.
Given a MOSFET with W=20μm, L=5μm, K=1.5, V_GS=4V, and V_th=1V. Calculate I_DS if V_DS is 3V. How does changing V_DS to 6V affect I_DS?
Show hintHide hint
Use the I_DS formula for saturation.
Question 6.
If V_GS is reduced to 2V in the above scenario, what will be the new behavior of I_DS? Discuss.
Show hintHide hint
Refer to the effect of threshold voltage.
